Using Histogram Statistics

The following table lists equations that apply to histogram statistics:

Equation	Statistic
	The number of cells is a calculated value that determines the number of bars to be displayed on a histogram.
	The cell width represents the size of each cell interval.
	The cell lower limit is the lower class limit for each cell (i) within the histogram. The first cell (i=1) must be calculated, and then subsequent cell limits can be calculated using the second equation.
	The cell upper limit is the upper class limit for each cell within the histogram.
	The cell tally is the total number of individual values in a cell.
	The cell percentage is the percentage of individual values in a cell.
